When sourcing water from a channel or storage pond, therises and falls in water levels that can occur essentially change the specifications for a pumping system, because these variations change the head. A single speed pump dimensioned to lift from the lowest water level will burn energy dollars when the level is high. A variable speed pump is on the other hand able to adjust its speed to compensate for changes in water level for the benefit of overall farm productivity.

With Grundfos’ assistance, farmers will get a system that will balance intake with changing water levels and demands to protect against dry-running, cavitation and motor failure.
